What’s the data science and technology behind Peak?
We record all ~40 billion DNS queries per year that are made to the core .nz servers from millions of sources.
These queries are automatically split into the different types of services – web sites, email servers, telephony
servers, Minecraft servers and more – using advanced pattern matching to produce a traffic score per service.
We scan the front page of every website in .nz and extract enough text to use in our machine learning
classifiers. These determine if a website is used for business and if so, what industry class it is in or
what type of not-for-profit it is. If it is a personal use domain then no further classification is attempted.
For the health check we scan every domain in .nz (currently over 670,000) and tests each one for over
50 different domain name configuration errors.
